"It'll be small and intimate for the wedding, and then we're throwing a massive bash for everyone in the states," she shared with Access Hollywood. "I've been planning as we've been leading up to this, so I think I have the wedding in order and now it's on to the party for the fun."

With Michael retired from swimming, the couple is now focused on spending even more time together as a family.

As for mom and dad, they are also excited to enjoy the next chapter of their lives as husband and wife.

"Now we get to have fun," Nicole shared with Cosmopolitan. "We get to enjoy parts of life that everybody gets to on a daily basis that we had to step away from so Michael could go and do what he needed to do."

She added, "We're still learning what date night is and we're balancing with Boomer. We love going to dinner. We love being home and cooking together. We're homebodies."
